SPECIFICATION forming paztof Letters Patent No. 628,751, dated July 1 1, 1 899.

Application filed September 16, 1898. Serial No. 691,059. (No model.)

To @ZZ wto'm/ t may concern:

Be it known that I, CHARLES A. BROWN, a citizen of the United States, residing at the city of St. Louis, inthe State of Missouri, have invented a 'certainnew and useful Improvement in Paint-Agitators, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to improvements in devices for agitating paints, and is designed for use in what is known as the dipping process, in which instead of having the paint applied by abrush the articles are painted by immersion. I am aware that it is not new to keep the paint in the tank in which the articles are immersed agitated by means of a revolving screw or beater located in the bottom of the tank, and I am also aware that it is not new to prevent the articles being painted or the tools used by the workmen from coming in contact with the said revolving screw or beater by means of a guard located directly above the said beater; but it has been found in practice that when the beater or agitator is at rest the heavier ingredients of the paint by reason of their greater specific gravity settle in the bottom of the tank and firmly embed in a more or less compact mass the said agitator. v

It is the object of my invention to provide a device which will prevent the heavier ingredients of the paint from settling about the agitator, so as to enable operation to be easily and quickly resumed after the device has been at rest.

Figure I shows a vertical section of my d`evice. Fig. II shows an end View of a central supporting-partition with the plates on which the paint settles shown in cross-section- Fig. III is an end elevation of said partition. Fig. IV is a top view of the plates on which the paint settles. Fig. V :is a perspective view of the plate-supporting partition and a portion of the plates on which the paint settles.

l is the paint-holding tank, designed to be It has a curved bottom 2, in which is the agitator or beater, which is secured to a shaft 4.-, driven by any suitable power. This agitator or beater 3 is placed close to the bottom of the tank l and is adapted to keep the paint constantly stirred or agitated. 5 are brackets secured to the sides of the tank 1 and on which the partition 6 rests. Similar plates 7 are placed at the ends of the tank and differ from the central partition 6 only in that the guides 8 and 9 are placed on one side thereof. The guides 8 are mere pins placed at 'the top of the partition and plates 6 and 7; but the guides 9 are in the form of ribs and extend approximately to the bottom of the said partition 6 and plates 7. They are curved upwardly at the bottom, and about midway their extremities are curved out of a straight line, as shown in Figs. II and III.

lO are pins placed just above the lower curved ends of the guides 9.

1l are plates constructed of thin material, preferably metal, and seated between the pins S lO and the guides 9.

Y l2 is a deiector which is placed longitudi' nally through the center ofY the agitator directly above the two central plates 1l.

It will be noticed that the plates ll are supported so that they are somewhat obliquethat.V is, at an angle with a perpendicular. Their lower edges are upturned to form pockets, and while normal, as shown in Figs. I and II, the main portions thereof form plane surfaces, yet the guides 9, which support them, are curved intermediate of their ends, so that upon the presence of Weight on the plates 1l they will sag or bend and conform to the guides 9. The pins 10 hold the lower portions of said plates and prevent the Same from swinging outwardly or upwardly. IVhen the heavier ingredients of the paint settle upon the said plates, they will be pressed in toward the guides or supports 9, and the lower edges thereof will be forced outwardly toward or against the inner side ofthe adjacent plate. Thus they form a protection to the bottom 2 of the tank l,and thereby prevent the heavier ingredients of the paint from settling-about the agitator. After the device has been at IOO IOv

heavier ingredients settled thereon up into the main body of the tank and thoroughly mix the same.

I claim as my invention- 1. Inapaint-agitator, the combination with a tank and abeater therein; ot' plates mounted in said tank above said beater, extending downwardly in edgewise positions and provided with pockets at their lower edges, substantially as described.

2. In a paint-agitator, the combination with -a tank andabeater therein; of plates mounted in said tank above said beater, extending downwardly in edgewise' positions at an angle to the perpendicular and provided with pockets at their lower edges, substantially as described.

3. In apain t-agitator, the eombin ation With a tank and a beater therein; of plates mounted in said tank above said beater, extending downwardly in edgewise positions and provided with pockets at their lower edges; and means for supporting said plates, said means being so constructed as to permit the depression of the central portions of said plates under the pressure of Weight applied thereto, substantially as described.v

4C. In a paint-agitator, the combination with a tank and a beater therein; of plates mounted edgewise above said beater, extending downwardly and provided With pockets at their lower edges; and a defleotor arranged longitudinally of and above said plates, substantially as described.
